Title
(EN) TWO-SIDED INDUCTIVE CHARGING COIL
(FR) BOBINE DE CHARGE INDUCTIVE À DEUX CÔTÉS
Abstract
(EN)
A device for inductively charging an electronic accessory includes a first portion, a second portion, and a spacer. The first portion includes a first transmission coil in a first plane where the first transmission coil is configured to generate a first magnetic field, and the second portion includes a first transmission coil in a second plane where the second transmission coil is configured to generate a second magnetic field. The spacer is positioned between the first transmission coil and the second transmission coil and between the first plane and the second plane. The spacer material magnetically insulates the second transmission coil from the first magnetic field.

La présente invention concerne un dispositif pour charger par induction un accessoire électronique qui comprend une première partie, une seconde partie et un élément d'espacement. La première partie comprend une première bobine de transmission dans un premier plan, la première bobine de transmission étant configurée pour générer un premier champ magnétique, et la seconde partie comprend une première bobine de transmission dans un second plan, la seconde bobine de transmission étant configurée pour générer un second champ magnétique. L'élément d'espacement est positionné entre la première bobine de transmission et la seconde bobine de transmission et entre le premier plan et le second plan. Le matériau d'espacement isole magnétiquement la seconde bobine de transmission du premier champ magnétique.
